Electric Bills & Data Centers:
The Real Story
Why market design matters more than data center growth — backed by SemiAnalysis data.

The PJM Crisis
$29 to $270 Per MW-Day — Overnight
PJM Interconnection operates the grid for 13 eastern US states and 65 million people. In its 2025/2026 Base Residual Auction, capacity prices jumped 9.3x — from $29 to $270 per MW-day. The result: households across PJM territory are now paying $25–30 more per month on their electric bills. The total cost of the auction: $16 billion.

Total Capacity Auction Cost
This price spike did not happen because electricity demand suddenly surged. It happened because PJM’s auction methodology changed how it counted available capacity, making 14 GW of existing gas plants “disappear” on paper — creating a phantom shortage that drove prices through the roof.

It’s Not Data Centers — It’s the Auction
PJM’s Simulated Forecasts Create Real Costs ✗ The Myth
“Data centers are driving up electricity prices everywhere.”
✓ The Fact
Only PJM’s flawed capacity auction converts speculative demand forecasts into guaranteed costs — and those forecasts are chronically wrong.
PJM’s datacenter load forecasts were cut by 800 MW in 2024 and another 1.1 GW in 2025. The projects that were supposed to materialize simply didn’t. Meanwhile, methodology changes to the auction’s accreditation rules made 14 GW of gas capacity “disappear” on paper — not because the plants shut down, but because PJM changed the math.
The problem is not that data centers exist. The problem is that PJM’s auction model treats speculative forecasts as guaranteed costs. Texas has more data centers than PJM territory — and no capacity crisis.

ERCOT’s Energy-Only Market Keeps Bills Stable
| Factor | PJM (Eastern US) | ERCOT (Texas) |
|---|---|---|
| Market type | Capacity auction (BRA) | Energy-only |
| DC growth | Rapid | Rapid |
| Bill impact | +$25–30/mo | Stable |
| Capacity price | $270/MW-day (9.3x) | N/A |
| Storm Fern | 21 GW lost (15%) | Grid held |
| Reform speed | Years (13 states) | Months |
During Winter Storm Fern, PJM — the grid that charges the highest “insurance premiums” via its capacity auction — lost 21 GW of generation, roughly 15% of its fleet. ERCOT, which charges zero for capacity and was widely expected to fail, held its grid. The irony is staggering: the states that paid the most for reliability had the worst reliability failure.
The states that paid the highest insurance premiums for grid reliability had the worst reliability failure. ERCOT spent $0 on capacity auctions, invested in real infrastructure, and kept the lights on.

Why IVDC Won’t Raise Your Bill
IID Operates Its Own Grid — Outside PJM and CAISO
The Imperial Irrigation District (IID) is a publicly owned utility that sets its own rates, operates its own transmission grid, and is not subject to PJM’s capacity auctions or CAISO’s market structures. The market design flaw that is costing eastern US households $25–30/month simply does not exist here.
IID Publicly Owned, Sets Own Rates $100M+ Developer-Funded Substation 862 MWh Tesla Megapack Stabilizes Grid $28.75M/yr Tax Revenue for Schools
Imperial Valley residents are not exposed to the market design flaw hurting eastern states. The IVDC is investing hundreds of millions into the grid at zero cost to ratepayers.
Data Centers Build Grids. Broken Auctions Break Bills.
The data is clear. Market design — not data centers — determines whether your electric bill goes up.
